SPECIFICATION forming part of Letters Patent No. 388,878, dated September 4, 1888.

Application filed February 21,1888. Serial No. 264.713. (No model.)

To aZZ whom it may concern.-

Be it known thatI, ALEXANDER H URTUBISE, a citizen of the United States, residing at Saginaw, county of Saginaw, State of Michigan, have invented certain new and useful Improvements in Sleighs; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in the construction ofsleighs, having for its object their increased durability, convenience, and utility, as well as their sim' plicity of construction and economy of manufacture, all of which I carry out-,as more fully hereinafter described, and more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is a plan view illustrating features of my invention, and Fig. 3 is a cross-section just in front of the cross-beam.

My invention is more particularly designed with reference to that class of sleighs employed in lumber regions for logging purposes, and consequently special adaptation has been kept in view to meet these ends and give greater strength to sleighs manufactured for these uses. I do not, however, limit myself to any specific construction of sleighs alone.

Accordingly A represents a runner.

B and B are raves, each constructed of a solid block, preferably of wood, and engaged upon the top of the runner and separated from each other to admit the cross-beam 0 being located between their adjacent edges. These adjacent edges are preferably constructed with square corners and straight faces, as shown. The cross beam is constructed preferably with corresponding recesscs,as at c c, to receive the said adjacent edges of said raves. Thereby the cross-beam is firmly held from lateral displacement.

Secured upon the top of the runner and beneath the crossbeam is a broad metal plate, D, made wider than the runner and forn'iing a broad bearing for the cross-beam in its connection upon the runner. It is found that heretofore where the cross-beam has a limited and the whole structure is very materially weakened under the heavy loads to which these sleighs are subjected. Such a tendency rapidly develops and increases, resulting often in the destruction of the sleighs; but I have found that the employment of a broad plate underneath the crossbeam projecting laterally from the top of the runner,properl y constructed and engaged therewith, entirely overcomes this tendency and effectually corrects the difficulty, preventing all liability ofthe runner tilting laterally under the strain communicated thereto from the cross-beam. This plate may be extended under the adjacent edges of the staves, so as to be held in place by the bolts b, by which the said staves are engaged upon the runners with additional bolts b.

To prevent the vertical displacement of the cross-beam, I employ a binder, E, consisting, preferably, of a chain so extended across the beam,its ends being suitably fastened,as upon the bolts b,underneath their nuts If. A chain is flexible, an advantage of special importance in logging purposes, being less likelyto break. The cross beam may be recessed, as at a, if preferred, to receive the binding-chain.

A sleigh so constructed is evidently very strong and durable, while also simple in construction, and has special adaptation to its work.

In addition to these features my invention also contemplates the particular construction of the runner and of the shoe engaged therewith. I have found it of special advantage in facilitating the construction of the runner that the adjacent edges of the shoe and runner be made straight from the rearend of the runner forward to the upward curvature forming the forward end of the runner, and I have also found it of special importance to construct the shoe F of greater thickness intermediate of its ends, so that the shoe shall be bulged or provided with a convexed running'edge. Such a construction strengthens the shoe beneath the cross-beam and permits its upper edge to be made straight withoutweakening the shoe, while its under edgehas a morelimited bearing.

To these features, constitutinga part of my invention, I lay claim in another application executed and filed of even date herewith.

The cross-beam is preferably rounded on its under side at the point of contact with the plate D, as shown'in Fig. 1. This tends to prevent too great rigidity as respects the engagement of the cross-beam. By extending the plate D at its ends under the adjacent portion of the raves the plate is held with great firmness.

What I claim is- 1. The combination, with a sleigh-rnnner, of raves engaged thereupon, a laterally-fin movable cross beam located between said raves,and a flexible binder to prevent the vertical displacement of the cross-beam, substantially as described.

2. The combination, with a sleigh-runner, of raves engaged thereupon, a cross-beam engaged upon the runner between the raves,said raves constructed with square adjacent faces, and said cross-beam constructed with corre sponding recesses upon its front and back sides, substantially as and for the purposes described.

3. The combination, with a sleigh-runner, of raves engaged thereupon, a cross-beam engaged between said raves and recessed to embrace the adjacent edges of the raves, and a 5. The combination, with the sleigh-runner and raves bolted thereto, leaving a space between them for the reception of the crossbeam, the cross-beam recessed to embrace the adjacent ends of the raves, ot' a plate wider than the runner and having a flat upper face, the said plate lying on the runner between the adjacent ends of the raves and having its ends projected under the adjacent ends of the raves, and a flexible binder extending'fromrone of the raves to the other over the beam, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses. ALEXANDER HURTUBISE. Witnesses:
